3 Description
The SimpleLink
™
CC2651P3 device is a single-protocol 2.4-GHz wireless microcontroller (MCU) supporting
Zigbee
®
, Bluetooth
®
5.2 Low Energy, IEEE 802.15.4g, TI 15.4-Stack (2.4 GHz). The CC2651P3 is based on an
Arm
®
Cortex
®
M4 main processor and optimized for low-power wireless communication and advanced sensing
in grid infrastructure, building automation, retail automation, personal electronics and medical applications.
The CC2651P3 has a software defined radio powered by an Arm® Cortex® M0, which allows support for
multiple physical layers and RF standards. The device supports operation in the 2360 to 2500-MHz frequency
band. The CC2651P3 has an efficient built-in PA that supports +10 dBm TX at 21 mA and +20 dBm TX at
101 mA (7x7 package). CC2651P3 has a receive sensitivity of -104 dBm for 125-kbps Bluetooth® Low Energy
Coded PHY.
The CC2651P3 has a low sleep current of 0.8 μA with RTC and 32KB RAM retention.
Consistent with many customers’ 10 to 15 years or longer life cycle requirements, TI has a product life cycle
policy with a commitment to product longevity and continuity of supply.
The CC2651P3 device is part of the SimpleLink™ MCU platform, which consists of Wi-Fi®, Bluetooth® Low
Energy, Thread, Zigbee, Wi-SUN®, Amazon Sidewalk, mioty, Sub-1 GHz MCUs, and host MCUs. CC2651P3 is
part of a scalable portfolio with flash sizes from 32KB to 704KB with pin-to-pin compatible package options.
The common SimpleLink™CC13xx and CC26xx Software Development Kit (SDK) and SysConfig system
configuration tool supports migration between devices in the portfolio. A comprehensive number of software
stacks, application examples and SimpleLink
™
Academy training sessions are included in the SDK. For more
